Bootstrap’s Inverse Navbar issue with IE versions less than 10. If you used the default navbar and encountered issues in Internet Explorer (like the navbar appears to be all black in IE only), check this out. Oh and this isn’t an issue in IE10, just IE9, IE8 and lower. The problem has to do with IE’s treatment of gradients specified in the boots…

Open up /css/bootstrap.css and look for this entry: .navbar-inverse .navbar-inner

In that style, change the filter entry from this:
filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#ff151515', endColorstr='#ff040404', GradientType=0);

to this:
filter: none;

That should make the navbar look as good in IE as it does already for Chrome, Safari and Firefox.
